કોઈ એક વિસ્તારમાં (x, y, z) m બિંદુએ વિધુતસ્થિતિમાન \(V=5 x^2\) Volt વડે અપાય છે, તો (1, 2, 3) m બિંદુએ વિધુતક્ષેત્ર \(\overrightarrow{ E }=\) _______ \(\frac{ N }{ C }\).

  1. A \(\hat{i}+2 \hat{j}+3 \hat{k}\)
  2. B \(-20 \hat{j}\)
  3. C \(-30 \hat{k}\)
  4. D \(-10 \hat{i}\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(-10 \hat{i}\)

Step-by-step Solution

Detailed explanation

(D)
\(\begin{aligned} & E= - \frac{N}{d x} \\ \therefore & E= - \frac{d}{d x}\left(5 x^2\right) \\ \therefore & E= -10 x \\ \therefore & E=-10(1) \\ \therefore & E=-10 i \frac{N}{C}\end{aligned}\)
